He also gave a radio interview to Triple J naming the top five "crazy" MPs and senators, with Mr Abbott - who he described as "a singularly destructive human being" - at the top of the list.

Peter Dutton, Angus Taylor, Kevin Andrews and Eric Abetz also made that list.

Mr Abbott received just 39 per cent of the primary vote in his former seat of Warringah. After preferences, Zali Steggall had almost 58 per cent of the vote in what has always been a super safe Liberal seat.

In his concession speech, Mr Abbott said: "It's also clear that in some, what might be described as wealthy seats, we're doing tough and the green-left are doing better.

"Where climate change is a moral issue, we Liberals do it tough. Where climate change is an economic issue, as tonight shows, we do very, very well."
